Sect leader Warren Jeffs was taken to a hospital in Las Vegas on Tuesday. Police wouldn’t say why and the real cause of his departure hasn't been found out yet. Jeffs was taken to the Sunrise Hospital and Medical Center in Las Vegas from an Arizona Jail.

The jail in Kingman, Arizona is 100 miles from the medical center and the imprisoned man was flown by helicopter to the hospital, where he was placed under armed guard by the Metropolitan Police Department.

Warren Jeffs, 52, is the leader of FLDS, a Mormon offshoot that practices polygamy. The Fundamentalist Church of Jesus Christ of Latter-day Saints has an estimated 10,000-members.

In April of this year, authorities found more than 400 children at the FLDS’s Yearning for Zion Ranch near Eldorado, Texas. Child protection said that they found a “pervasive pattern” of sexual abuse which was forcing marriages between underage girls and older men.

Jeffs was convicted in Utah, in November, to two consecutive terms of five years to life in prison, after being convicted on two charges of raping in connection with a marriage he performed in 2001. He now awaits trial for five counts of sexual conducts with a minor, four counts of incest and one count of conspiracy to commit sexual conduct with a minor.

It seems that he tried to kill himself while he was in jail. He refused food and drink for a month, developing ulcer. He then tried to hang himself and after that he banged his head and threw himself against the wall.
